Automatically Change Forum Signature

[rm -rf]

Ahoy Y'all,

I'm planning to code something that will automatically change my signature to the contents of a .txt file on my computer.

I know C++, C#, Java, and Python.

Any ideas how to start this?

I don't think the forum supports any way of hooking into something like that as far as I'm aware

For various reasons such as Cloudflare, login/session cookies and the signature form in general being lame this is a giant pain in the ass. 

 

But I was bored...so here's a Python script that sets your sig to the current time. You'll need the Requests, BeautifulSoup and cfscrape packages to run it, then just set your username and password at the top of the file. Then you can alter the main function to use some file instead of the current time.

Interesting...the only reason I can think of that you'd be getting that error is if your signature changing page is different than mine or you're getting redirected differently. Could you go to this page https://linustechtips.com/main/settings/signature/ copy the source and post it somewhere.

 

edit: better yet if you could add the line 

print(res.text)

before the line

soup = bs4.BeautifulSoup(res.text, 'html.parser')

and post that output.

It's working now, I just had to turn off my two factor authentication.

Good to hear. Also, if this is the program that you're trying to run hidden, you can start a Python script using pythonw.exe instead of python.exe and it will run without popping up a new window.
