wa 'alaykum salam wa rahmatullahi wa barakatuhu
Although name changes do occur on TTI -- I ask those who request it to re-consider a few times and their reason for doing so - before they request. The reason being that the only way to change your name is by PMing the Admin and having him personally alter it. Now, although this is a viable option, it must be remembered that he is often busy and to personally cater to many people is difficult.
( I mean if many people at a time began requesting name changes it would be hard to accomodate all that and would take up much time. )
So if you would like a name change, please PM the Admin along with if you could a reason why? As that would make it much easier...
