Artsoft links and hosts the latest full custom artwork games, Zomis and BD-fans host the rest. There isn't a central list of all RnD levels, they're all mixed up...which is a shame. (BD-fans was close, but hasn't updated for ages)
As flump said...
I don't know anywhere I could host files (I think my ISP has some space).
I'd like to see Holger, or maybe Zomis or someone similiar create some space for levelset and artwork uploading - an official site for all things RnD. Somewhere centralised.
Yes, that's right. There were several documentations there yet, were't there? But no one did a continuous one (except of Zomis, but not very seperated, as already said...)
Zomis, couldn't you create a files archive with several categories instead of one single huge collection of everything that was ever done? Categories like levels, levelgroups, artwork sets, sound and music sets, etc. ? Only a suggestion..
(BTW: I'm not very skilled making such an archive, I'd do it as well if I knew how)
