I would try out different sites including the ones set up by @BOLDnPurPnBlacK and @purpleflock.com. However, I caution you to use an email generated solely for this purpose as the sites may not immediately be secure, but as long as you use aliases and don't divulge any private information about yourself, you should be fine. I use Russel Street report but not their discussion boards. So, get a feel for these boards and stick with one that you feel gives you the most value.
