Investorshub message boards do not use OpenSSL. We run on Windows boxes that are unaffected by the Heartbleed bug. Examples of SSL that you will find on IH proper are the credit card processing pages and the login process.
The ADVFN mothership does use OpenSSL, but the boxes I've personally checked are and have been using versions that were unaffected by the bug.
Nothing to worry about except our usual mind control rays :-)
