well its a nice idea from u.
but there are several issues i see in your videos.
-lack of information. u dont tell everything about the stuff u explain. as example the market tutorial, u just say "the market is a place where u can buy things" well which stuff and so on.
-u dont prepare for the videos. it seems u just wanted to record something and upload it, to get hopefully some clicks. an example to let your videos look better : make a piece of paper where the most important things stand and try to not say all these "ehhh" that sounds weird. try to keep explaining and if u get out of your concept look on the paper and ull remember how to go on. that will let your videos look more smooth.
also the topics u make videos about are "meh" im sure most people didnt got a problem with this stuff, cause its simple and there are already tons of explantations.
(if u want to make forum videos i would rate u to show the diffrent forum sections, for what they are and what u can do there actually. i think that would be more helpfull then this ^^.)
