I know many sites do accept guest posts, collaborations, or even sponsored posts, but Ask Leo! does not.
Ask Leo! is me: Leo.
One of the things that set Ask Leo! apart from others is that all the articles have been written by me, Leo Notenboom; it is 100% based on my knowledge, experience, opinions, words, and philosophy.
And at this time there are no plans to change that.
Because I get so many solicitations, repeated requests will be marked as spam.
Thanks for understanding.
