Role Play Shoutboxes?

[Neonzumi]

And what do you look for in atmosphere when it comes to messaging with text?

A picture of a bar/restaurant/conference room above the shoutbox and character photos next to the messages.

Also the possibility for people to read up if they are interested.

Public character and story developement.

Same as the communication channel and the already existing watering holes. Those could also be done in skype.

Also, its easier for new people and strangers to join in if its on the forum.

I think this is a pointless idea.. just use skype, its hard to believe you don't need it, its 2015 keep up.

I have skype and you made a pointless post.

So could someone who actually has any useful information other than "dude there is skype you know man, dude" answer the question: Is it technically possible to make multiple shout boxes in this forum software or not, or are there good browser based alternatives that give a neat RP feel?

I think it is possible most probably, but it would take too much work for something not so important. There are other things Devs need to worry about.
While using skype people tend to simply have links on imgur of their char pics and important things. While rather then a single picture to describe a place, like in the BD Club there is a simple text description of the whole Kyoto bar which gives a better idea of what the place looks like and gives a bit more room for imagination.

If you are looking for an alternative to it, something like you have described, no. I never heard of any software or website with those kind of capabilities. Tho you should try googling it, something might come up.
