I have not been able to post update photos either for a while and have pretty much given up.
Several years ago when many of the regular contributors to this site stopped posting I thought that would be the start of the decline for TRMA. We know many moved/created Facebook groups which allows for instant photos, quicker responses and a greater audience. You only have to look at the amount of posts in the TRMA threads which are 1-2 a week at best. .
I myself am also guilty, having my own Titanic model Facebook page to act as a build blog for my current project. I would much prefer to share here. TRMA has been a vital part of my model building experience in the past and i am grateful. It has been a helpful resource, with great content & information and posting by experts and other knowledgeable contributors. However it looks, feels the same as it did years ago with no new content, tech features, archive updates etc. With the problems you are experiencing it feels like it could be the final nail in the coffin. This is a big shame as it appears Facebook is the preferred choice and will be the ultimate winner unless something can be done.
I have no knowledge about how websites operate so i apologise if i speak out of tone but i does feel like a complete revamp with greater publicity would be hopeful outcome. However as Bob says a Facebook TRMA may be the answer. 'Cant beat them ,join them'.
