These type of questions is what I like people to ask, some people may say they are "simple" questions but it is better to be safe and see what is allowed and what might be deemed spam.
Let's look at my set-up for introduce yourself creations:
Code:
Welcome [NAME] to the Freedom! Forums.
[MESSAGE]
[ADDITIONAL]
This is just a format template, you could start with your message at the beginning of the post, maybe @ tagging the thread creator?
MESSAGE: What I look for in the message section is a few sentences up to a paragraph relating to how the user introduced themselves. For example, if they talk about gaming, maybe include some games that you have heard/played before, try to intrigue conversations with the user.
Sometimes they can be a bit awkward, either just introducing their channel and not themselves.
For this, I sometimes look at their channel talking something about one of their features, either their thumbnails or their banner etc..
Basically, try to make your reply relate to what was said or what the person creates.
ADDITIONAL: This format is only used if they need to edit their post since they didn't follow the rules or maybe I tell them that their YouTube Sub Button is broken and they should fix it.
If someone does not introduce themselves and is asking for subs, just remind them with a quick "As this is the introduce yourself section, we would like you to introduce who you are, not your channel" - or something close.
This is because I don't want you to be classed as "Backseat moderating" by telling people they are breaking the rules and ordering them to edit their post.
Hope this helps, you may have seen some of my messages around the introduce yourself section so you can see my examples of what I mean in action.
