Official Boxers' (and Boxing Scene Users) Twitter Pages

[MeiXiang]

I got hold of an Android cell phone about 2 weeks ago and it's made me more and more social with following my favourite boxers. Anyway. I apologise if this has been done before but I'm looking for Official Boxer Twitter Pages as well as Boxing Scene users. This will help us find official Twitters instead of searching and sifting through the thousands of fake accounts and also help us to interact even more. Here's my list of Official Twitters and feel free to add some on that I may have missed - I'm still new to Twitter and I haven't added every boxer on yet. Also feel, free to add in your Twitter in the format given below:
