Comfortably use juick.com (microblogging service) in Gajim.
Juick is a web service that takes XMPP messages and creates a microblog using those messages as entries. There’s no registration, no signup, no hassle. You simply send a XMPP message to email@example.com and it creates a blog based on the username you sent from and begins recording submissions. See juick.com.
This plugin adds a menu to juick links in messages and adds the ability to display images and avatars. The key combination Alt + Up in the input textbox allows to insert the number of the last message (comment or topic).
