Great plugin. Got very much excited to get a try.I have some couple question and suggestions for plugin development.
a)If join request is send to signature thread.Will it wait for the campaign manager approval or will directly start up counting right after join request?
b)Most campaign managers don't count spammy posts or posts that are irrelevant to thread or violates one of rule in signature thread so in that case the plugin you are developing will not provide the actual earning .
c)Many signature posters have different taste about signature campaigns. Some like daily payment, some like monthly and some like weekly and in same way they also their choices are widen with the rules of signature campaign so I think it will be better to make a kind of form about signature poster preference and then search automatically the best campaign.
d) In case if signature poster is kicked will the bot will be back to search a new campaign?
e) Most of campaign has minimum/maximum posts .So I guess it will be better to make a kind of progress bar for that.If postcount<minimum then progress bar becomes red otherwise green.
I really like the plugin features but there are also a lot of things to develop.GL
