Thanks for responding iionly. I started experimenting with TinyMCE enabled, because seems the best solution cause implements a word count, and then installing a TinyMCE character limiter plugin, but I don't know how to convert it to limit words instead of characters, and neither can't make shows the characters count. As not get results, then I have done many tests with TinyMCE disabled, so that the text is entered as in Thewire the text box whith no options to format. I have not gotten it to work, unfortunately.

I've tested the character limiter plugin briefly yesterday. I also haven't managed to get the number of remaining characters to show (mainly because I haven't understood what this plugin expects as input ID - Elgg input or tinymce input specific?). But the character limitation worked at least.

As Elgg 1.8 has a word counter already implemented in the bundled tinymce plugin you might be able to expand this word counter to a word limiter by studying the code of the character limiter plugin.

Or this code snippet might help you: http://snipt.net/tamewhale/add-word-count-and-limit-to-tinymce. It already implements a word counter + limiter and it's implemented in the same way as the Elgg tinymce word counter.

Yeah, I get it to work at least as limiting, but then it's easier to use 'maxlength'. Anyway I'll back to try the TinyMCE plugin to see if I get to count words, but I tried and I can't understand how can I do it, my knowledge is rather limited. Anyway thank you very much for the help iionly ;-)
