Unfortunately, TWHL is dying. And I think most of these ideas have great potential, but no individual idea is good enough on its own. I say we do the following:
1: Get one or two more moderators to check the forums for spam, people going seriously off-topic, flaming, swearing etc. They would be part-time, but should check the forums as much as possible, keeping the moderating time realistic (Obviously, they don't have to ruin their holidays by going to internet cafes just to sort out the forums).
2: Get a team of moderators for the map vault. They could read the comments for the map, if the reaction suggests the map(s) is/are effortless, pointless, showing off, or flooding/spamming the vault, they should email the person who submitted about the problem, and if necessary, delete the map. At the moment, I have to wade through several pages of pointless maps just to find one or two that I'm looking for.
3: Encourage new people to look at tutorials before asking questions. Bring back the old forums! Originally, there was a General Mapping forum, Stuff forum, Site comments forum, and a forum for each individual tutorial (Obviously, keep the new Maps and mods forum). The individual tutorial forums meant that people would at least see a list of tutorials in the forums before going to answer questions that have been answered in the tutorials. Encourage new people to search the forums for help as well.
4: Break up the vault. Have a CS completed section (Most maps tend to be CS), a HL completed section (Second most popular), HL mod completed section (EG: Opfor, BS, TFC, Spirit etc.), Problem section (HL, mods, and CS), Example section (HL, mods, and CS), Unfinished section (HL, mods, and CS), Completed model section, Unfinished model section, and also include a mod section for any HL mods people have made. This will make finding things easier, and remove the chance of having to wade through several CS maps to find a TFC map, for example.
