Well don't take this explanation as 100% accurate; I'm just the filing amphibian for the story space. With that disclaimer in place:

As far as I am aware there are 3 different spaces available each with a different purpose.
1. The story space. According to the description given to me along with the passwords for the filemanager this space is for screenshots needed for the two new forums. Signature pics etc were on the 'don't allow' list, hence me saying they are not allowed. If something is put through the uploader linked in the first post in this topic it ends up in the story filemanager and I transfer it over to the actual hosting space. The space is 25MB total with 15.6MB used.

2. The frog space is just a small 10MB space where I put the screenshots for my guides. The only people with access to this space are TosaInu and myself. I can give the password to assistants if I want but so far there is no need. To put anything in this space you have to log into the filemanager using the correct name/password for this space and then manually upload it. That is the only (as far as I know) way for anything to get to this space.

3. There is a third space I know very little about. All I know is that this space has a signature pic on it and no one manages it in the same way as the story space. I have no idea how to get anything onto that space. This is probably the space TosaInu was talking about for avatars and signature pics.

There could be another 100 spaces out there I don't know about. I don't know what order they were set up in, what the relative sizes are etc. To be honest this doesn't bother me - there is a limit to how much filing you want to do Two sets of log ins and passwords for essentially the same thing is fine, any more and I’d probably get them mixed up
