you should do mixes instead of just playlists
dimension expander vst
ALL THE MELDAPRODUCTION PLUGINS TOO THEY ARE ACE
also ambience vst
I'm not sure I want to exclude quite so many projects. But it might make sense to limit any external VSTs to free ones and, critically, to list any used in the description. But just as a guideline. If you start making rules and trying to enforce them you'll just stop people from bothering to share ...
I'm sick of seeing posts where you have to download a bunch of samples or have to have certain VSTS, it should be common sense not to upload projects with such things because not everyone has what they have. I think we should all agree on some guidelines for projects and maybe somehow enforce them?
