SMS integration like PM integration

[space?]

Good day to you all,

I wonder if there is a way to offer a SMS function to the members, so they can add their cellphone number to their profile and then send SMS instead of Private Messages to other members.

Would be quite an effort to insert into vBulletin, wouldn't it?
I'm not that bad in PHP, I think if you can tell me what to do and what to modify in vBulletin I can do it - and offer thus SMS-Integration-Modification to you all.

But I'm really a nerd with vB, was using WBB for years since a short time ago

Have a look at the attachment, its a very simple(I'm at work, sorry had to go fast) mindmap. The Modification itself would be the red lines, connecting the forum with the gateway.

The SMS Gateway is already working
Hope you could follow.

Kind regards,
Stephan
