If you want to chat with other Wiktionary users, you may find some of them at #Wiktionary. Feel free to pop in and say hello; there is normally someone who will answer. If no-one does, it is probably because they are all away or asleep. Remember that everyone is in different timezones, so try again after a couple of hours.
In order to access these channels, you will need an IRC client. Some of the more popular ones are ChatZilla and mIRC, though there are many others. If you don't wish to install a client, then you can get to the channels through webchat.freenode.net
On #wiktionary and #wiktionary-gfdl there is a bot called LinkyC, who performs many useful tasks, including providing links styled [[like this]], so you don't need to install wiki-link script (just type as though it were wikitext). LinkyC can also tell international time; just say !time. If you want to know what else it does, say !LinkyC?.
On #wiktionary we also have Edgar. If you see him online, you can ask this bot for definitions by typing define <word>, i.e. define fnord. If you have questions about Edgar, ask Mutante.
#wiktionary-gfdl has its logs published under the GFDL and so discussion there should remain on topic. Often, if a discussion on #wiktionary seems to be getting important and involved, the participants will migrate to #wiktionary-gfdl so that they can refer to the discussion, should the need to arise later.
