I'm temporarily without a pc, and have added a few new contacts on my Android phone. However, the Android client does not have the ability to create new meta contacts, leaving me with multiple entries for each new contact. I can't seem to do so in the web client either.

Is the web client able to create and manage meta contacts? If not, it would be a very useful feature, especially with PCs fading in importance.

The web client can not (unless it's been updated and I have no seen). The android client CAN.

Press and hold down on your contacts name, this will open up a menu for that contact, click on MOVE and you will have the ability to move that contact to an existing group or contact, thus creating a metacontact.

Perhaps I should have posted "creating meta contacts". As you pointed out, the Android client can move individual contacts into pre-existing groups and meta contacts. However, other individual contacts are not allowable targets, which prevents me from creating a new meta contact.

Moving a contact onto another contact will create a metactonact. I'm sure of it, i think. I can't verify it right now as I can't log into Trillian on my phone.

As logical as that sounds, normal non-meta contacts do not appear when choosing as targets to move a contact.

Okay I'd have to look again, I thought I saw some. However I'm using a beta build that is not available to the general public, so it's possible if I was correct that the feature just hasn't been implemented yet.

If meta contact creation is to be added then that is great news.
