Judging from the last time the Op of that thread last came online and the last reply in that thread I highly doubt that the bot is still active, so it would be better for you to tryout Tryninja’s telegram bot since it’s still active and also has more features than the one in your post.
When you start the bot and you’re asked for your ID use this 3578185, it’s your ID.
I sent 2 PM's to Maggiordomo writing the subject as subscribe and in body: hello
But not got any response for 1 day.
Why try to use that particular notification when you already have a good suggestion made to you in your first thread? The OP of the thread for which you dropped the link here has been inactive for years, which probably means there is a possibility of the bot being outdated as no fixing or update has been done to it over the years.
The V2 Bitcointalk Supper Notifier is really an easy-to-use bot; you don't even need any coaching from anyone before you can use it. I will advise you to save yourself the stress and use the one recommended to you by the first person that commented on your post.
