Many folks won’t click on web links from new members because they look spammy or self-promotional. They also invoke too much effort: you’re asking us to poke about in the developer toolbar while trying to filter out all the extra bumf of an unfamiliar codebase. Sadly that’s not very appealing. Make it easier for us to offer assistance. Help us to help you.
