Does anyone know if iti s possible to manage nicklist state? Twitch recently completely removed basic IRC features like NAMES, USER, WHO, USERHOST and even ISON so now I need to add each nick manually into the list from ON TEXT event. Thing is - I'm not sure hopw to do that without creating custom sidelist window and using /aline.

Any ideas?

Not to use nicklist for twitch? It wasnt reliable before and it isnt now.

Thanks!
But why stop here? May be avoid using mIRC at all? Or whole IRC in general?

If mIRC will be as unreliable as nicklist was - yes. But none of IRC clients can handle nicklist properly (if they were not made for twitch specially somehow).

mIRC is lacking a feature that would allow scripters to pull such information from the web and fill the nicklist as expected. The feature suggestion can be found HERE

Custom window with sidelist it is then.
Thanks.

Use an ON JOIN and ON PART event to add/remove nicks from a hash table.

When you have on-join and on-part events - you have no need in making another nicklist. C.O.
