No. Sorry, but no.
I know that many sites do accept guest or even sponsored posts, but Ask Leo! does not.
Let me explain why.
Ask Leo! is … well, it’s me: Leo
There are many, many technical support sites out on the internet.
One of the things that set Ask Leo! apart from others is that all the articles have been written1 by me, Leo Notenboom.
For better (or for worse) one of the values that Ask Leo! brings to the internet is that it is 100% based on my knowledge, experience, opinions, words and philosophy.
As I said, for better or worse. 🙂
And at this time there are no plans to change that.
Thanks for understanding.
