The Legend SRD has always been the Legend Core Rulebooks, rather than a plain old document.
What happened on the Chaosium thread, I think, was that someone could not see Legend listed as an OGL set of rules, so assumed that it was no longer OGL.
Now, we all know that Matthew Sprange has stated on many occasions that Legend could always be under the OGL, so we are confident that this is always the case.
As a matter of interest, in the same thread, Jeff has stated that Legend is an entity all on its own and is not connected with the MRQ SRD, so is a perfectly valid OGL product. Whilst we all knew and assumed that anyway, it is good to see it in black and white. I know that some people have been reluctant to write things for Legend due to some uncertainties about the Legend OGL status and this should clear that up.
