I'm busy with Bloodlines right now and also was told to wait with any external missions and campaigns until Raider Wars has finished testing. 

Bloody love Bloodlines!  Thank you so much for getting it working.  Just my luck that two of my favourite franchise, Bloodlines and S.T.A.L.K.E.R. were broken bug-fests at launch.  Modders - fixing stuff for free that paid devs left broken. 

I simply said don't upload the missions to the data folder we're using for Raider Wars. 

But as far as I know you can't play out of the tmp folder and I assumed you wanted to finish Raider Wars first.  After all in the end all missions have to be in the data folder and all other content has to be in the other folders too!  Or could it be made that when not using VPs anymore, each campaign could get a subfolder to keep some order? 

You can put the missions in the main folder to test them, just don't commit them. 

Yeah, but what about all the other files in the VPs?  The missions are all ready to run anyway, I fixed up the Starfury Missions, the Vorlon campaign, the Shadow campaign and Mag's traning missions.  The problem is how to commit them and when? 

You can do whatever you want with your own local copy.  Just don't commit until we've got Raider Wars working.  If you're not going to do any further work on those missions, just commit to the temp folder and we can move them later. 

Looking at the files contained within an individual commit would be the first thing I would use for that information. 

But what happens if something is overwritten?  As I see it, until now local files were packed into the VP archives, so even if MAG changed a file that is used in Raider Wars, it wouldn't have mattered.  I we extract all VPs into the same folder, there is the risk that something breaks, so can we use subfolder for mission packs or campaigns? 

You also can't overwrite things permanently with SVN, if it somehow happened you could check out an older revision to get it back.  It's perhaps not the most ideal solution for this kind of temporary mission storage but it seems preferred to losing your work altogether.  If you would you could put your work into named folders inside the temp folder maybe, one for each vp you had.  Would keep everything separate then.
