My favourite is the third yellow box, because the live link to openwrt.org is more prominent here.
I'm afraid, this can only be done with ssh access to wiki.openwrt.org.
If however the wiki subdomain is transfered to the current openwrt.org servers, then it's no problem. In fact, I already put that yellow box in the copy of the old wiki which resides on openwrt.org, i.e. once the subdomain is transfered, it will automatically show up.
I want to stress that this is really a live link (clickable) instead of simple text as with the current yellow box on wiki.openwrt.org.
Thanks for the summary.
We now have a plan, and the only thing that is hindering us in executing the plan is the missing support for the transfer of the wiki subdomain...
How can we now move forward?
