Both the site and forums (www.myspleen.org/forums) are down - perhaps it could be something to do with a server move mentioned on there not long ago?, IIRC.
Hopefully they’ll both be back up soon. It is probably worth checking the www.myspleen.org/forums every now and then - that may likely be the service that is online first (and a good place to ask any questions / look for updates & info etc re the MySpleen site itself). 👍
Edit: both the MySpleen site and forums seem to be back up and working fine 😃
