Motagator is my website, so thanks for the comments here.
I initially started the site to promote the bands and musicians that I play with, or am associated with in some way. I then realised that it would be good to open it up to all so as to help others bands and to get to listen to some new music. The webspace and most of the facilities are free, but there is a modest annual subscription for those who want more webspace and want to be able to use all the site features. But from this, I only hope to cover the costs of running the site - I'm not 'in the business' as such.
"I just read in their "new user agreement" that by signing with them you give them rights to perform, and distribute your work. So I was wondering if anyone here has ever dealt with them."
Just to explain, the T&C is a 'standard' document that I used so as to cover all legal aspects of the site. However, I realise that this section of it is not relevent to what I'm doing and is maybe putting some people off, so I've now removed it.
So, feel free to register and upload your tracks etc.
