My suggestion is to bring back the old style of the "Your Quota" box
The problem is many users don't click on the "more details" link
Then they try to upload a file type or file size that is now allowed, and they get an error and write a thread that the upload is not working for them,
i know they are not very smart.
The old style of "your quota" was a lot easier to see the types of files allowed for uploading, members quickly read it,
i can't remember exactly which version was this way, ( a few back)but i remember this is how it originally was,
i thought it was much better before, alot more convenient, now i have to click every time, and i always forget which files types are allowed and what size, so i find myself often clicking that link,
