I obviously remember more things that I might not ought to than the language itself (I mean language learning) however I know you @elizabeth_jane once have written that you first created one profile and loged into the forum with one device (I can't remember was that any iDevoce though) and then you created another profile due to not being able to log into the forum with the first one. I'm not sure why (I forgot) but I think it was that you forgot the password but the main reason I believe was that with the app on iDevices you members at one time couldn't log in if you were already logged in with another device or PC. So this might be the reason you created another profila.
I believe the first profile was @elizabeth_jane and afterwards you've created that other @elizabeth_j_corbett_ . That's also why this second profile remained without the picture. There's no way to merge those two profiles I believe (I'm almost 100 sure) so I believe it's the best to leave things as they are. on both profiles you have a lot of posts so it would be pity to do anything and risk to spoil something or even delete posts.
I actually have got used to your two profiles so I don't get distracted anymore. I'd suggest keep log in on each device as you did before as they probably already have saved passwords. I'm sure there's no such problem with dual identity.
Well two of you might get next book written and ready for us faster than just one. ...
