I had created bot app using Circuit SDK and got a sandbox in circuitsandbox.net. To create a bot application I went to "Manage Applications" -> "Custom Apps" and created a bot app. It works great but only way to add bot to conversation I found is to type his full mail in "Add Conversation" menu. Is it possible to found him like common user (searching by his name)?
Bots can be added via email as you noted, and not by its name. But the new way to add bots to conversations is via the sidebar. This will be available very shortly, probably in a week or two.
