<p>Encouraging (pressuring - yes, it can be viewed as such) users to accept an Answer has been outlawed on StackOverflow for good reason. It is up to individual users whether they want to accept an answer or not. If they don't want to, that is up to them.</p>

<p>For example, the accept rate is now not displayed for a user in the Q&amp;A to stop people berating users that have a low accept rate.</p>

<p>A timely reminder of how the SE sites work via a link to <a href="https://stats.stackexchange.com/faq">FAQ</a> is OK for new users, but doing so for every unaccepted question would just clutter the site.</p>

<p>Other than that, vote on good Answers, downvote or comment on bad Answers, users visiting those Questions will be informed by the voting even if an accept is not forthcoming.</p>

<p>Finally, I don't buy into the idea that once an Answer is accepted the Q&amp;A is complete. A better Answer may be forthcoming, or an alternative approach or solution provided. I often check back against interesting Q&amp;As through the Favourite mechanism to see if there have been updates. CV, like the other SE sites, is an evolving beast, and that doesn't end with a click on the tick.</p>
