Auto-posting bot software for a forum

I need an auto-post bot software. It will be use specifically to make automatic postings in forum.asianbookie.com. The purpose is to have usernames with a lot number of posts to gain higher rank status. The bot must be able to, 1. Make automatic reply post every 1 minute or 3 minute intervals (Giving more intervals would be an added points). Look at the forum. For example [login to view URL], this is in the English Football forum (32). If you change it to 33 which is Italian Football forum, the link would be diverted back to the "[login to view URL]" So the bot must be smart enough. The user will only give the thread/topic id. For this case, it is 2057436. If I want to post on 100 threads, I will just type 2057436 - 2057535. The bot will then do its job. It must be able to find the correct forum. If after searching all the forums available the bot not able to find the thread, then it will proceed to the next thread id. 2. In the message field (the content of the message post), I must be able to type for example "good luck". then the bot will make automatic post on every thread (as in #1) with the same content (good luck). 3. (Optional)- the bot will hopefully could be used for several web browsers. Or a few might be used simultaneously. For example, username/nickname: jacob . and another for username/nickname: bilic. *the bot does not need to create usernames. Usernames and passwords are ready. For those who can do this, you may bid for this project. This project is worth $150-$350. But submit any bid as long as you are qualified and able to do the job. This project might be closed sooner than the bidding period if I get suitable freelancer.
