xlogin is only of use if you have linked your mIRCStorm to another in a botnet.
By doing \'/msg xlogin \' rather than \'/msg login \' it logs you on to all the bots in the botnet, this saves the need to login to each bot.

To Link bots, do into the partyline on the bot (DCC Chat) and type \'.+bot\' (including the . and +). Intructions will follow. After adding the bot type \'.link \'. Dont forget to add the listening port and ip on the main setup on the bot you want to connect to.

Note: the current beta version only support a max of 2 links bots. The next version (non-beta) has a unlimited number, supporting large botnets just like the eggdrop bot.

Hope this helps,

If you need any more help, i suggest http://www.mircstorm.co.uk where we have busy forums with people who can help.
