Going to group up every issue that i have found people complained about or have issues with here, so the admins have an easier way to figure out what the community wants.

1.
Colour and font

The colour / font choice is extremely poor and hard to read for some people, proof by the last comment on this trade, http://www.tf2outpost.com/trade/27875885#latest he said i didnt have a trade offer link when i clearly did, proving it is hard to see for some users. also when putting a "~" in the trade notes it goes above instead of in the middle which is fairly ugly, change the font to Arial or something.

2.
Mobile trade bumping

it is almost impossible for a user to bump or delete a trade while on the mobile website, the bump/delete button are visible only on hover, which you cant hover on mobile so you have to guess where the buttons are. A new user will be unable to figure out where it is and be unable to bump there trades then will stop using the website altogether.

3.
Mobile user searching

Doesnt exist. There are 2 search options on the normal website, for items/trades and then for users. Both search buttons (top nav bar and side navbar) have a search button on mobile, both of which are used to find items/trades and not users. So if you are looking for a certain user, its impossible.

4.
Australiums

Australiums currently dont have the gold 'badge' beside them indicating that they are infact australium, making it harder for people to sell them and causing low balling since people think they are normal stranges.

5.
The nav-bars

The sideways extending thing was a mess which you guys fixed but the right bar still has some issues, like for example, what do these yellow bars even mean? http://puu.sh/nDoPf/65f7d45cbf.png
A new user or even me for example have no idea, are they the percentage of trades which include those items? if that's the case does every trade include ref then? Those bars tell us absolutely nothing and are confusing. also the top "search" bar looks ugly slightly transparent, when you can see your items in a trade through it, it just looks bad.
also the left nav-bar has no reason to scroll up when you hit the bottom of the page, it should be fixed by the top of the screen, not the bottom. ex: http://puu.sh/nDpis/7cb701dcef.gif

6.
Bugs / general glitches.

Some people have glitches where all there buttons / icons are overlapping (favs,views, etc)
also the red warning bar which appears when you "cant bump this trade it hasn't been 30 mins" sometimes appears with no text or warning on it when you are just browsing.

FIXED 7.
Major bug with clicking on users names.

sometimes when you click on a comment which was on another comment it brings you to the first commenter's profile, ex
user A comments on person B's trade
user B replies to user A's comment.
Click on user B's comment to go to there profile
Get sent to user A's profile
this happened to me on this page http://www.tf2outpost.com/trade/27566407 on the 2nd last comment with trade owner saying he will accept the trade. it also happened on other trades as well

when I was grabbing proof for a report on someone i almost linked the wrong profile because of that user glitch.

Temp Fixed 8.
Unknown user (glitch still exists but it apparently fixes itself in minutes)

Some trades for no reason get a "unknown owner" on them so you cant bump or close the trade. this happens randomly and gets fixed on its own after a couple hours or days. But it still returns occasionally.

9.
Mobile Comment Section - Impossible to read

For the comments in a trade, they get indented, and if its a reply to a comment, they get indented again, but the problem is its by a fixed amount instead of a percentage. So on mobile the comment section is literally one word per line. Im using a 5.5 inch phone 1920 x 1080px, and its just cancer to look at. http://puu.sh/ovQ6n/814dd77bd0.jpg

If anyone else has discovered another bug / issue with the website post it below and ill update the notes.
