Well, I’ve developed a twitter bot, @Twity001, same as Della bot that provides with useful information.It’s an auto reply bot.So you have to send a direct reply message to this bot to get information.

The service Twity has provided so far including Weather Forecast, Stock Market and TV List. To get start, you have to follow @Twity001, then send it an @reply with the commands to get the info u need.

Here is a short commands manual for using Twity with correct formats.

Simply tweet @Twity001 ? or @Twity001 help to get the help list

Weather Forecast
