IRC Jevalbot
Jevalbot is an irc bot that can run J expressions.
Where can jevalbot be found?
No-one is currently running jevalbot all around the clock, but at least two of us sometimes run it when we go on irc. When we are running them, here is where you can find them.
The bots can be found on the freenode irc server (hostname irc.freenode.net port 6667) on channels #jsoftware and #ijx. As detailed on Community/IRC, the first channel is primarily intended for conversation with humans, while the second one is for conversing with bots, so if you want to experiment with some J phrases, use the second one. Look for the nicks evalj and ijx, the first one is the instance ran by B Jonas (b_jonas on irc), the second is by Dan Bron.
How do I use jevalbot?
The simplest usage is just to address the bot on a channel it's joined. Type its name followed by a colon (or right bracket or right parenthesis) followed by a self-complete j phrase. For example, suppose that evalj is joined on a channel, and your nick is b_jonas. Here's an imaginary conversation that could happen on the channel.
< vmye> evalj: i.5 < evalj> vmye: 0 1 2 3 4 < vmye> evalj]i.5 1 < evalj> vmye: 0 < evalj> vmye: 1 < evalj> vmye: 2 < evalj> vmye: 3 < evalj> vmye: 4 < vmye> evalj] ,/,.&' '(?~10$5)C.'pears' < evalj> vmye: psrea asepr rpase erpas serpa paesr respa psera pears eapsr
As you can see, the replies are prefixed with your nick. You'll soon find out that long replies are truncated to avoid flooding:

< evalj> vmye: ...
Phrases executed like this are always using a fresh interpreter instance which is thrown away afterwards. The default j profile is not loaded, so you won't find the names defined by the library, nor names you've assigned to in previous lines. (A few settings like output truncation are still set.)
< vmye> evalj: NL
< evalj> vmye: |value error: NL
< vmye> evalj: NL =: 10{a. NB. if a phrase produces no output, you get an ok prompt when it's executed
< evalj> vmye: |ok
< vmye> evalj: NL
< evalj> vmye: |value error: NL
For this reason, sessions were invented.
[And then that was the point where I was lazy to continue the documentation and left it in this stage. I've written some more docs much later to Community/IRC, so go there and read about sessions there, but I'm still lazy to collect the docs into a proper form, so if you don't understand something, just ask.

How do I run my instance of jevalbot?
You can download the source of jevalbot from [1]. )As jevalbot is still in development, I sometimes upload new changes to that address.) Extract the tarball. Make a copy of the configuration file and edit it. Run the script with ruby using the name of the changed config file as the first command-line argument.
I'm currently using an i686-linux machine with ruby 1.8.5.
Where can I ask questions
You might find B Jonas on the freenode irc network with nick b_jonas, or you can write email to the address (#~]~:1&|.) 'ambrus@@mmaatthh..bbmmee..hhuu'
