Feel free to recycle, you don't need to ask. (I actually recommend you don't ask, because I'm not here very often.)
If (and only if) you include recognisable parts of my stuff in something you upload, please include a direct link to my version. This is particularly important with edits made for/with different game versions. You don't need to explicitely mention me, just give people the link.
If you use my stuff, please upload the result to a free, accessible, noncommercial site with no more restrictions than these. Sites covered in ads do count as commercial. Sites that require giving away private data (like Yahoo Groups) do not count as accessible. Sites that require having bought stuff to register (like EA) do not count as free. Ask Me, Thank Me, and other Me Me Me stuff does count as restriction.
