In the previous sandboxes, it was suggested that if you had 3 upvotes on your sandbox submission, it was ready to go.
I have written a few sandbox posts recently. Of these, all have been commented on and one has had 4 votes - this is clearly enough. However, two have had 0 votes and two have had 1 vote.
I have occasionally bumped the posts in chat, but this seems to have had little or no effect.
How do I make more people notice my sandbox submission? Do I need to?
