When to make thesis available for public access? I have recently finished my thesis and submitted to both university and national thesis center.

However, it is not online yet (probably there are many thesis pending). Should I wait for the thesis center to make it available or can I just put it to my website?
Unless your university has a policy that explicitly forbids it (which would be very strange), you should feel free to post your thesis online as soon as it has been officially submitted and accepted.
