Deprotection Or Add Cheats (and maybe you can make a dynamic page that gets rid of some fields if you select 'Deprotection')
Map Name
Map Link (or maybe add a feature to be able to upload to fileserver from the form?)
Cheatpack to add
Map Description
Custom Additions
and when a user hits 'Submit', it automatically makes a nice tidy thread for the user saying some like:
[Request]{MAP NAME}
Hi! I would like you to add {CHEATPACK TO ADD}'s cheatpack to this map. The link to this map is {MAP LINK}. {DESCRIPTION}. I would also like you to do the following things with the map: {CUSTOM ADDITIONS}. Thanks!
greets {USER}
And maybe you could remove everyone's permissions to post topics (in the requests section)!
Haha i'm slightly copying dekar with the 'greets' things

Anyway, just a suggestion for you to consider and hopefully make!
The reason I'm suggesting this is because there are a lot of n00bish requests that have no description, no title (in the title), no link/attachment and crap grammar -.-
Example:
Title: Hax th1sM4p!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
H1 4ll!!!!! Pl0X h4x d1s m4p 4nd hurry up pl0x!!! d0on"""T k33p m3 w4171ng xD xD xD Xd Xd d4 m4p n4m3 1s d074 4lls74rs 6,36!!!!!!
------------------------------------------
It took me ages to convert as many letters I could into numbers -.- I'm crap at writing crap.... and incase you can't read that it says:
Title: Hax thisMap!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
H1 all!!!!! Plox hax dis map and hurry up plox!!! doon'''t keep me waiting xD xD xD Xd Xd da map name is dota allstars 6,36!!!!!!
