contact # / msn is personal stuff..
if you click on the user id, you can see his contact number if the person has allowed everyone to see it. so thats not a problem having the contact number under the user id or just a click away.
similarly for msn, you have the option to mail him directly, and hence if the person is ok with you, he'll reply and you can get his id.
soooo many people (of all types) visit pakwheels, we cant just give away this important information.
as for editing. i guess its one hour.. but after that, you can just hit report abuse.. mods hain na!!
