I have just heard that the Gospel Coalition have suspended their plans to place back-issues of Themelios on-line. The problem is that the authors own the copyright to their articles not the journal and so they cannot appear on-line without each author giving his/her permission (I was already aware of this from my work on the articles).
Your Help Needed!
I have offered to assist by putting them in touch with the authors I have been in correspondence with. If you are a Themelios author and would like your article(s) to appear on the Gospel Coalition website please email me at rob(at)biblicalstudies.org.uk and send you the address of my contact at the Gospel Coalition. Please pass this message on to any Themelios authors you might know.
