I know this subject has been discussed many times but recently I’ve seen too many WTB or Sale/Trade postings that included phone numbers, addresses and e-mail addresses.
This is a good way to get scammed. Anyone, not just forum members can use this information. It was recommended many times by the forum moderators to only post your contact information in your profile. That way you need to be a member in order to access the information.
OGR moderators do screen individuals wanting to join the forum and this at least this provides some sense of security.
