One thing about this site is they also promote other sites. Take the Top 75 addons page ... they link you to other sites if they don't carry it here. They also won't allow you to be sent to places that they don't trust themselves.

I'm sure if Cairenn and the others have a problem with MobMap they will delete these links as well as close this thread.
FYI ... I just downloaded the files and ran them through McAfee AV (Updated today as well) and they came up clean.
