Thanks guys, and OK I'm happy to keep things running (donations welcome - will get that setup on the site again )
Working in the IT industry, I know all too well how old versions of software tend to lend themselves to the unscrupulous ones out there, giving them known (and unpatched) exploits they can target. This version of the forum went end of life in terms of support a couple of months back, and would like to keep it up-to-date and as secure as possible to limit attempts from hackers ... that's my main driver for upgrading .. security!
