Invalid/Non-portable acyclic aromatic SMILES =[edit]

Do you mind if I correct the SMILES for Sulfur monoxide from 'o:s' back to 'O=S'? Generally SMILES line notation reserves lower case characters and colons to indicate aromaticity in cyclic conjugated systems, and indeed many cheminformatics toolkits reject or misinterpret 'o:s'. In SMILES generated by Dave Weininger's/Daylight's original toolkit, aromatic atoms only appear in ring systems. The reason I ask is that it was your edit of 25 July 2011 that changed the SMILES to the current representation, and I didn't want to revert anything unless I'm sure that change was unintentional. Where did you come across (or how did you generate) 'o:s', by the way? May I please have your permission to edit similar SMILES issues as I come across them? Many thanks in advance.

Sure, go ahead? You don't need my permission, but I thank you for letting me know. (talk) 08:46, 13 August 2016 (UTC)

ArbCom Elections 2016: Voting now open![edit]

Scale of justice 2.svg Hello, Plasmic Physics. Voting in the 2016 Arbitration Committee elections is open from Monday, 00:00, 21 November through Sunday, 23:59, 4 December to all unblocked users who have registered an account before Wednesday, 00:00, 28 October 2016 and have made at least 150 mainspace edits before Sunday, 00:00, 1 November 2016.

The Arbitration Committee is the panel of editors responsible for conducting the Wikipedia arbitration process. It has the authority to impose binding solutions to disputes between editors, primarily for serious conduct disputes the community has been unable to resolve. This includes the authority to impose site bans, topic bans, editing restrictions, and other measures needed to maintain our editing environment. The arbitration policy describes the Committee's roles and responsibilities in greater detail.

If you wish to participate in the 2016 election, please review the candidates' statements and submit your choices on the voting page. MediaWiki message delivery (talk) 22:08, 21 November 2016 (UTC)
