Hello. This is quite unfortunate, because I've been enjoying the experience so far, and am considering paying for a month or two of the "Pro" extras, to practise more thoroughly, once I've finished going through all the free stuff. And if I think that there are a lot of bugs here, I might not feel like doing it So I guess I'm trying to help you guys make a living here, which you do deserve to do, for all the effort involved.
The particular bug (I think) I'm looking at right now is here on sections 3.4 and 3.5 of the Ruby. Unless I'm being really stupid and missing something, it looks like the .include? and .gsub! methods are not properly set up. Well anyway, my screen looks like this, not accepting include?:
and I have one with the same message for .gsub! , but your forum doesn't let me put more than one image.
I hope that it's me missing something stupid, but if not y'all need to take a good look. There was something similar on the Python tutorials, on the file input/output section, where the .txt file wasn't present. Take a look!
