Personal website and/or blog
Having your own site, especially with a domain name that closely resembles your cam name, is very handy. You can host your own blog which your members can read and keep up to date on your life (well, as much of your life as you share via your cam persona) and is a great way to announce upcoming events, sales or special shows.
Make sure when you purchase your domain, you also invest in domain privacy with the domain name registrar that you use.
If buying and hosting your own site is too advanced, a service like Blogger may be a good option for a personal blog. And as mentioned in another section, Tumblr is a popular choice for personal blogging, but is also more focused on followers and image sharing.
