I really like to connect with people but if I don't know you and don't know why you want to connect with me then I won't! If you are an artist and you want to connect with me please send me your website address otherwise I won't follow up your invitation.
If you're an artist and you don't have a website then for your own sake set one up asap. I can recommend Weebly. As someone who has to research artists websites on a regular basis my advice would be to have a simple, clear layout plenty of good quality images - put your text (bios, statements etc on a separate page) and have very straightforward navigation.
If you look at my own websites:
www.fiongunn.org, http://www.bigsmallartists.com/www.intimatetransgressions.weebly.com and www.sewinginstreatham.weebly.com you will see the kind of artists I collaborate with and the kinds of projects in which I'm involved. So if you want an 'agent', a gallery or someone to promote your work commercially and if your work falls into the category of commercial then I'm not the person you should want to connect with!
