Hello everyone!
If someone posts an answer to your question, mark it as the solution!
That makes it easier for others to
a) figure out the solution for their own problems
b) know which topics still need answering
The solutions author will also receive a shiny badge for their profile!
Sometimes the solution would be your own answer!
So feel free to just pop that solution on yourself 
Other times the way to solving an issue is a very iterative process…
Having a dedicated solution helps others, with similar issues, resolve the problem quickly.
It would be totally awesome, if you could write a quick summary in this case.
Maybe the repetition also helps you understand the process better? 
This is covered in the FAQ too, if you want to give them a read!
Have a nice day!
