2169 is not a good place to receive mail.
You should not ship packages there unless you can ensure that someone expecting the package will be present at the time it arrives.
There are two potential mailing addresses for Noisebridge, one listed at Donate and Noisebridge and another listed at Utilities. FIXME: someone should find out which of these boxes actually gets checked and remove the other one from the wiki!
..... noting the above caveats (thanks!) - here is tentative info (to be more appropriately filed elsewhere)
Official (??? maybe not - read above FIXME) Mailing Address:
NOISEBRIDGE 2261 MARKET ST # 235-A SAN FRANCISCO CA 94114-1600
NOISEBRIDGE 2169 MISSION ST # 3 SAN FRANCISCO CA 94110-1219
